...Behold, that goodness is in his hands and he controls the decision, whether to educate himself and understand or to remain naked of all wisdom, even though the heart and mind are contained within his body. It is readily apparent that there are two things created sharing similar functions: Man's intellect and and The Torah that imparts the intelligence.
With regards to The Torah it is stated (Jeremiah 23:29): "'Is not My word like a fire?', says Hashem." He made it known to us, the truth of the matter, that The Torah is literally like a singular light given to the Jewish people to find illumination with, not like other foreign wisdoms and secular information which are merely facts which can be comprehended though intellectual toil. However, The Torah is divinely holy whose existence is elevated in the highest heavens. When a person involves himself in The Torah below (this world) it illuminates his soul granting him access to lofty treasures, treasures of The Creator, in a reciprocating manner. As man works to understand The Torah works to change man.
